Problems solved by technology

The disadvantage is that although there are expansion joints around the floor, since each floor is fixed by floor nails, the deformation of the floor cannot be transmitted. When the floor shrinks, there will be cracks between the joints. Expansion and each plate is fixed and cannot move and squeeze each other to make the floor arch, pull up the floor nails, make the floor loose, and make a sound after stepping on it
In order to avoid this situation, leave a seam between the boards, so that the dirt can be embedded, and the liquid cannot be removed. At the same time, the floor cannot be migrated once installed

Embodiment 1

[0011] There are holes drilled on the floor strips, and the prestressed wires pass through the holes on the floor and the floor clips (the floor clips can be installed between the joints between the boards or slotted in the direction intersecting the drilled holes on the board to install the floor clips on This position), the lower end of the floor card is stuck on the keel (the keel can be grooved, I-shaped, T-shaped, with slots or long holes on both sides of the mouth, etc., as long as the floor card is satisfied, it can be easily fixed and slid , When the floor card is elastic, it can also not slide) When the prestressing wire is tightened after connection, the prestressing is applied to the floor and fixed with anchors, or the anchor itself has tension and fixation functions. At this point the floor will be provided with pre-stress in three directions, namely in two directions at the level of the floor and downwards. For the installation of the keel, it can be fixed on the...

Abstract

A floor capable of effectively preventing floor deformation and convenient to disassemble and assemble is composed of strip-type floors, prestressed wires penetrating through the floor, and anchorage devices installed on the end portions of the floor. Prestress is exerted on the floor by the tensioning prestressed wires.

Description

technical field [0001] The invention relates to a floor installation, which is convenient for installation and prevents cracking and deformation of the floor. Background technique [0002] At present, the known floor structure is to fix the floor on the keel with floor nails, and the plates are engaged by tongue and groove. The disadvantage is that although there are expansion joints around the floor, since each floor is fixed by floor nails, the deformation of the floor cannot be transmitted. When the floor shrinks, there will be cracks between the joints. Expansion and each plate is fixed and cannot move and squeeze each other to make the floor arch, pull up the floor nails, make the floor loose, and make a sound after stepping on it. In order to avoid this situation, seams are left between the boards, so that dirt can be embedded, and the liquid cannot be removed. At the same time, once the floor is installed, it cannot be migrated. Contents of the invention [0003] ...
